In the Debate that ruins Obama or Romney? Romney loses his cool while Obama keeps his cool and says "You mad bro?" or Romney makes Obama look scared and weak.
Sadly, debates never get that good.
I'll give you three debates where things got that good. The Republican debate in South Carolina(the one where Newt 'hit it out of the park' with regardsto his ex-wife's interview), the debate where Romney got into a "Don't talk while I talk" argument with Rick Perry, and umm... the third one, I forget. Oops.
